The regret utility matrix for 2022 data.

This study illuminates the multifaceted influence of Chinese in Africa, driven by the imperative to understand the strategic and economic ramifications of this rapidly evolving relationship. Motivated by the critical role Africa plays in global geopolitics and resource dynamics, alongside Chinese expanding international influences, the research aims to quantitatively and psychologically assess the decision-making processes underpinning this engagement. Adopting a regret theory-based Multiple Criteria Decision Making (MCDM) framework, the study evaluates Chinese impact across 49 African countries from 2018 to 2022, employing six economic indicators to capture the breadth of Chinese activities. Through meticulous normalization, regret utility computation, and total gap analysis, the methodology affords a systematic ranking that reflects the varying degrees of Chinese economic influence. The findings uncover pronounced variances in the level of Chinese engagement across the continent, with countries like Nigeria and Egypt showcasing substantial influence convergence with the theoretical model of ideal economic partnership, whereas others like Cape Verde indicate minimal influence. Contributing to academic and practical discourse, this study not only provides a methodological blueprint for analyzing geopolitical influences but also offers insights that policymakers can leverage to optimize their engagement strategies with Chinese. It foregrounds the interplay between empirical economic data and behavioral economics within international relations research. The study acknowledges limitations, primarily in data availability, which may not capture the full scope of informal economic interactions. It proposes further research to enrich the understanding of the Chinese-Africa nexus through longitudinal studies, integration of qualitative data, and expansion of the analytical model to encompass broader socio-economic impacts and more diverse indicators.本研究旨在剖析中国在非洲产生的多维度影响，其核心动因在于深入理解这一快速发展的双边关系所带来的战略与经济后果。鉴于非洲在全球地缘政治与资源格局中扮演的关键角色，以及中国不断拓展的国际影响力，本研究旨在从量化与心理层面评估支撑这一互动关系的决策过程。本研究采用基于后悔理论（regret theory）的多准则决策（Multiple Criteria Decision Making, MCDM）框架，对2018至2022年间中国在49个非洲国家的影响力展开评估，选取六项经济指标以全面覆盖中国在非活动的范畴。通过严谨的归一化处理、后悔效用计算与总差距分析，本研究的方法论可生成系统性的排名，以反映中国经济影响力的差异化程度。研究结果显示，非洲大陆各国的中国参与度存在显著差异：尼日利亚、埃及等国与理想经济伙伴关系的理论模型呈现出高度的影响力契合度，而佛得角等国则表现出极低的影响力水平。本研究可为学术与实务讨论贡献价值：不仅为地缘政治影响力分析提供了方法论蓝本，还可为政策制定者优化对华互动策略提供参考依据。本研究凸显了实证经济数据与行为经济学在国际关系研究中的交互作用。本研究也承认存在局限性，主要在于数据可得性问题，该问题可能无法覆盖非正规经济互动的全部范畴。最后，本研究提出后续研究方向：通过纵向研究、整合定性数据、拓展分析模型以涵盖更广泛的社会经济影响与更多元的指标，从而深化对中非关系的理解。
